I ordered this onesie for my 10 year old son and he absolutely adores it!! He is almost 5'2 and 130 lbs. Size 30 in men's pants. This fits him perfectly! I didn't expect the tail to be so BIG though! Honestly, it just makes it even more perfect. If you're wanting something to just hang out in or something to wear for a costume, this is definitely what you're needing.

The mouse onesie is irresistibly soft and cozy, with a plush interior that feels great against the skin. The little ears and tail add a playful touch without being over-the-top. It’s roomy enough to lounge in comfortably but still has enough structure to feel put-together rather than sloppy.

Can be worn as a onesie for lounging/sleeping or worn as a costume. It's made of a super soft fleece feeling material on the inside and outside and is easy to put on and zip up. It has a zipper up the front, a mouse themed hood and is comfortable on both the legs and body. It's made of a light to medium thick fabric that has good warmth and feels nice on. Once on you probably won't want to take it off- it's that comfortable. Looks like a real mouse and has the ears and tail. Overall- super comfortable and cute costume.
